Zong Yu was stunned: "I don't know these things, could it be that the virus mutated during the transmission?" ”

"It's impossible to mutate so quickly." Qi Min shook his head again and again: "If it is a mutation produced with the host, then it should be reflected in him." ”

"Well, this is a useful clue, and only by identifying the first infected person can it be possible to trace down the person who spread the virus." Zong Yu nodded: "You help me get that student's information, it's best to use the name of the review to find out why he recovered so quickly." ”

"It's easy to do." Qi Min shouted at a doctor: "Doctor Wu, help me call Principal Zhang, and say that I am looking for him." ”

"Hey!" The doctor trotted out, and in a moment brought with him an old man with glasses.

The old man seemed to have the temperament of a literati, gentle and elegant, with a kind face, and when he came in, he asked, "Old Qi, is there anything else to order?" ”

Qi Min pointed: "Lao Zhang, this is Professor Zongyu, the professor has something to talk to you about." Saying that, Qi Min looked at Zong Yu: "Professor, if you have anything, just ask Principal Zhang, he is my old classmate, I'll go over there first." ”

Zong Yu nodded and stretched out his hand: "Hello Principal Zhang!" ”

President Zhang smiled bitterly: "I didn't expect the professor to be so young, oops, it's really the back waves of the Yangtze River pushing the front waves, hey, the professor, it's really... Let you see the joke, I've never encountered such an unexpected situation in my whole life, you are experts, you have to help me! ”

Zong Yu shook his hand: "Principal Zhang, don't worry, didn't Dr. Zhao Yunlan already bring the vaccine? As long as the virus is sanitized, it will be fine. ”

Principal Zhang sighed: "Hey! How could this happen? Is it really like what is said from the outside that Yonghui Pharmaceutical Factory deliberately released poison in order to sell drugs? Then don't pick on our school, how can I, the principal, explain to the parents of the students with dozens of nearly 100 lives? They're all kids! ”

"President Zhang, the matter has not been clarified yet, let's not speculate first, I know more or less about Dr. Zhao Yunlan's personality, there should be another hidden reason in this matter, our top priority now is to sort out the ins and outs of this matter, and do a good job in the aftermath, I just have something to ask you for help."

"I can't talk about helping, just say what the professor wants me to do, I'm still dizzy now!"

"Principal Zhang, I want the information of the first infected student, can you help me check it?"

"Ah, this doesn't need to be checked, I remember, it's a first-year freshman, see Wang Haiyang, that kid, it's just a good thing, the whole thing is a little gangster, I wonder if he got infected with this virus somewhere."

"Wang Haiyang? Then I'll check it out. Zong Yu pressed his watch: "Check that the person named Wang Haiyang is a middle school student." ”

"After investigation, there are 569 middle school students with the same name as Wang Haiyang, please reset the search criteria."

"So many of the same name?" Zong Yu was stunned: "The first year student of Canghai Middle School." ”

"After investigation, there are four people with the same name in the same area, please click on the avatar to continue searching."

Zong Yu hurriedly put his wrist in front of Principal Zhang: "Principal Zhang, look at which Wang Haiyang it is." ”

Principal Zhang pointed: "The second and fourth are a bit similar, it should be... The second one. ”

Zong Yu hurriedly pressed the second avatar: "Wang Haiyang, born in Yinglong Town, Canghai City, father Wang Zhao Kai, mother lives in Jinmei, now Canghai Junior High School is in the first grade, has been forced to work three times for fighting and molesting women, my father has violent tendencies, alcoholism, gambling... ”

"It's a bad record, it's really not a good boy." Zong Yu said with a smile.

At this time, the watch rang again, it was Lin Qi's call: "Hey? Lin Qi, how are you over there? ”

Lin Qi's anxious voice came from the other end: "Brother-in-law, it's over, Ma Quan is dead, he was poisoned, what should I do now?" ”

Zong Yu was also shocked when he heard it: "How did you do it?" Can the Public Security Bureau still be poisoned? He's the most important part of the story, and what can he do if he's dead? It seems that this person deliberately wants to deduct all this on Zhao Yunlan's head, and now he is really powerless. ”

Lin Qi was taken aback: "Huh? What about Yan'er? Brother-in-law, you have a lot of ways, think about it and see what other ways there are, we know that Aunt Yunlan is innocent, can we just watch her go to prison? ”

"Have you checked the lawyer who contacted Ma Quan yesterday?"

"Checked, the bottom is clean, I'll check it carefully, brother-in-law, do you want to check his wife?"

"His wife was abducted and trafficked by him, and he also had a motive to kill him, check, okay, you can get busy first, and then contact him if you have something."

Zong Yu sighed: "How is this? Ma Quan is dead, who else will know the inside story? Could it be that Zhao Yunlan really can't be saved this time? Who else? Who else? His wife? Let's wait for Lin Qi's news first. ”

President Zhang was puzzled: "Professor, what's wrong with Wang Haiyang?" ”

Zong Yu shook his head: "It's not Wang Haiyang, we're talking... Zong Yu's eyes suddenly lit up: "Yes, there is him, although it is more troublesome than asking directly from Ma Quan's mouth, but there is still hope, I will go to him." ”

Principal Zhang hurriedly said: "Professor, you can't go to him now, you want to ask where the virus is infected from his mouth, hey, you better give up, that guy doesn't know if he really doesn't know or pretends not to know, if he can ask, he would have asked it a long time ago." ”

Zong Yu was stunned: he is probably the only breakthrough in this matter now, he can't startle the snake, he has to think of a perfect plan, what should he do? Yes, get close to him first and win his trust, but he is a student or a boarding student, do you want me to pretend to be a junior high school student? Or pretend to be a teacher? No, that kind of leather child will definitely not be close to the teacher, so it's better to pretend to be a student and let Ying'er give me a disguise.

After making up his mind, Zong Yu hurriedly said to Principal Zhang: "Principal Zhang, I'll ask you for a favor again, I'll pretend to be a student, and you will arrange me to Wang Haiyang's class." ”

Principal Zhang looked confused when he heard this: "Professor, what are you planning to do?" ”

"I want to try to get close to Wang Haiyang, and unknowingly find out the source of the virus, now it is very important to find out the source, otherwise Dr. Zhao Yunlan will suffer an injustice, you have to think about it, what are the consequences of Dr. Zhao Yunlan's failure to provide the vaccine in time, she knows that taking out the vaccine will make those false accusations more like that, but she did not hesitate to take out the vaccine as soon as possible in order to save the student's life, I must return her innocence."

"Professor, I understand that, but ... You don't look like a middle school student, Wang Haiyang is not a fool. ”

Zong Yu thought for a while: "He's not a fool, then I'm a fool, just say I... When I was born, I was born with a lack of oxygen and my brain was broken, so I didn't go to junior high school until I was in my twenties, do you think this explanation is reasonable? ”

Principal Zhang was very embarrassed: "Professor, you are a student, which teacher dares to give you a lesson?" This... Let's take a different approach! ”

Zong Yu shook his head: "This is the only way, besides, you know about it, you can't let the teachers know, it turns out that what kind of teacher is still what kind of teacher, otherwise Wang Haiyang will suspect it, and my plan will be all in vain." ”

Principal Zhang hurriedly said: "Professor, our school is divided into classes, and students like Wang Haiyang must be poor students, so the teachers are also the worst... This one... ”

Zong Yu saw Principal Zhang's concerns, and said with a smile: "Principal Zhang, I'm not here to study, the teachers are fine, the students are fine, and even if there are any irregularities, I won't talk nonsense, you can rest assured, as long as I figure out the source of the virus, I don't know anything else, as long as you listen to me, don't secretly adjust the change, just pretend that you don't know anything, remember, God knows this, you know I know." ”

Principal Zhang was helpless: "Okay, then tell me when you come, and I'll lead you over when the time comes, hey... Professor, you... It's really embarrassing for me. ”

Zong Yu smiled: "Don't be embarrassed, I thank Principal Zhang in advance, then I'll report when classes can resume." ”

Principal Zhang nodded: "When the virus is done, you can resume classes first, and talk about the aftermath slowly, then the day after tomorrow, just on Friday, you can find out the situation first and use the weekend to adjust." ”
